TECHNICAL FIELD

The present disclosure relates to an apparatus for cleaning human bodyorifice, more particularly, relates to an electric orifice cleaningbrush.

BACKGROUND

In the embryo period, the umbilicus region is the only channel for anembryo to connect with its maternal body and get blood, oxygen andnutrition. Though after the fetus is given birth and the channel is cutoff, the umbilicus region still has very close ties with the baby'sorgans. The umbilicus region is the thinnest part of the abdominal walland has no subcutaneous fat. However, it has abundant blood vessels.Through scientific research, people have found that there are about 1400kinds of bacteria parasitizing in human being's navels, more than 600kinds of which are unknown. In our daily life, we seldom care about ournavels, nor do we clean them frequently, which give very goodopportunities for bacteria to live and proliferate. Different peoplehave different types of navels, which can be classified into convexnavels and concave navels. Especially, for a deeply concave navel, it ismore prone to accumulate fouling inside, and it is very easy to get hurtand become infected when being cleaned off fouling.

These years, as people are paying more and more attention to human bodyaesthetics, they are more likely to choose the umbilical holelaparoscopic surgery as the abdominal surgery, which raises higherrequirements for cleaning the umbilical hole.

At present, before surgery the umbilical hole is cleaned by manuallydipping a dry cotton swab in turpentine, mainly rubbing the wrinkles onthe wall of the umbilical hole and its bottom part, and repeatedlycleaning these parts using different cotton swabs until fouling cannotbe observed. Due to the special anatomic structure of an umbilical hole,it is relatively difficult to be cleaned. The traditional way ofcleaning using cotton swabs along with turpentine and alcohol maysignificantly irritate the skin of a patient. As a result, oftentimesred swelling of the skin can be observed. Also, it is not easy to usethe thick head part of a cotton swab to clean the bottom part of alacuna, and detachment of cotton flocks from the head part of the cottonswab may produce new foreign substances easily. Moreover, thetraditional way of excavating longitudinally to clean the umbilical holemay have the potential risk of hurting the soft and tender skin at thebottom of the umbilical hole.

Further, in some other surgeries, it is also necessary to clean thepatients' orifices. For example, for removal of earwax and foreignsubstances from ear, the traditional way of rinsing and excavating stillposes certain risk to the interior structure of an ear. And somecraniocerebral surgeries involving nasal cavity need to open surgicalroutes through the nasal cavity. However, current method of cleaning anostril still has drawbacks, such as cleaning is incomplete and it mayirritate the patient significantly. For surgeries involving the perinealregion, such as abdominoperineal resection or repair of rectovaginalfistula, it is necessary to clean the perineal region. However, theanatomic structure of the perineal region, featuring plentiful wrinkles,as well as fecalith obstruction in the patient, may be the causes ofincomplete cleaning of this region. And this also makes it verydifficult to do surgical disinfection. With the advancement of surgicaltechnologies, to reduce a patient's trauma and maintain the wholeness ofthe patient's skin as much as possible, surgeons use natural orifices ofhuman bodies as surgical routes more and more frequently, so as to avoidlarge scale skin trauma. This kind of surgery is referred to as naturalorifice transluminal endoscopic surgery (NOTES). However, as naturalorifices of a human body are not like those exposed human organs, it isnot easy to clean and disinfect these natural orifices. For thesenatural orifices, traditional ways of cleaning, such as rinsing, usingcotton swabs and gauzes, also bring the similar problems such asincomplete cleaning and irritating the skin, etc., which occur incleaning the umbilical hole.

SUMMARY

The present disclosure provides an electric orifice cleaning brush tosolve the above-mentioned problems of not being able to completely cleanhuman body orifices and easily hurting skin. The cleaning brush issuitable for patients who need to be cleaned and disinfected in varioussurgeries. Its main function is to clean off the persistent fouling onthe body surface that are hard to get rid of. It is effective incleaning some narrow recesses or orifices on the body surface, such asumbilical hole, armpit, ear hole, etc. The mechanism behind this productis, for example, producing friction with skin surface to break upfouling by way of vibration, while at the same time distributingdisinfectants such as turpentine or alcohol across the body surface,thereby jointly achieving the goal of completely cleaning relevantparts. Its micro-vibration function is capable of facilitating thebreak-up of the fouling and more effectively dissolving it in theturpentine. Meanwhile, as no excessive longitudinal force will beproduced in the course of vibration, the risk of cleaning umbilical holecan be reduced. The dense arrangement of brush bristles makes it easy toadsorb fouling. As a result, fouling will not be accumulated in the deeppart of the umbilical hole. Also, material of extremely lowdust-generation is chosen for producing brush bristles and thus,self-cleaning will not produce additional foreign substances.

DETAILED DESCRIPTION

In the following, reference will be made to the drawings of theembodiments of the present disclosure, to clearly and completelydescribe the technical solutions of the embodiments of the presentdisclosure. It is obvious that the embodiments as described are merely apart of but definitely not all embodiments of the present disclosure.All other embodiments obtained by a person skilled in the art, based onthe embodiments, fall within the protection scope of the presentdisclosure, provided that obtaining these embodiments requires nocreative work of such a person.

FIGS. 1 and 2 are an exploded view and a side view, respectively, of anelectric orifice cleaning brush in accordance with an embodiment of thepresent disclosure (bristles are not shown in FIG. 1). The orificecleaning brush includes a motor 10, a motor holder 11, a sealing ring12, an eccentric shaft 14, and a brush head assembly. The brush headassembly and the motor holder 11 are mounted onto the housing 13. Agroove for accommodating the motor 10 is disposed on the motor holder11. The motor 10 is fixed in the groove within the motor holder 11. Thesealing ring 12 is located between the motor holder 11 and the housing13.

There are holes disposed at the bottom central parts of the motor holder11, the sealing ring 12, and the housing 13. When assembled, the drivingshaft of the motor 10 successively penetrates through the holes on themotor holder 11, the sealing ring 12, and the housing 13, and its endextends outside the housing 13 and connects with one end of theeccentric shaft 14. The other end of the eccentric shaft 14 deviatesfrom the center position and is connected to the brush head assembly asa the driving shaft for the brush head assembly.

In the present embodiment, the motor 10 connects with the brush headassembly through simple components such as the driving shaft and theeccentric shaft 14. The driving shaft of the motor 10 rotates and drivesthe eccentric shaft 14 to rotate, which in turn drives the brush headassembly to rotate. In this way, relevant energy loss is relatively low.The eccentric distance of the eccentric shaft is between 0.2 mm and 1mm, for example, is 0.4 mm or 0.6 mm. Being driven by the driving shaftof the motor, the design of the eccentric shaft enables it to rotatearound the driving shaft of the motor and to revolve on its own axisrelative to other fixed components in the meantime. By way of aself-lubricating bearing 21, the eccentric shaft 14 is positioned at abottom central groove of the brush head assembly. Therefore, it cancause the brush head assembly to move. However, it can be understoodthat, in other embodiments, the eccentric shaft 14 may be replaced byanother eccentric component such as an eccentric wheel, and its anotherend may be connected to the brush head assembly after being connected toother transmission components.

As shown in FIGS. 1 and 2, the cleaning brush's brush shaft portion issubstantially at a right angle to its brush head portion. However, itcan be understood that, in other embodiments, it is also feasible thatthe cleaning brush's brush shaft portion is designed to be at an obtuseangle (such as an angle of 120 degrees, 135 degrees, or 150 degrees), oreven at an angle of 180 degrees, to its brush head portion. In someapplications, these designs may be convenient for an operator to use.

As shown in FIG. 2, the sealing ring 12 has a hollow structure, and bothits inner side and its outer side take the form of disk structure 25.Its inner portion is a funnel-like hollow chamber 26, in which alubricant is filled. This not only achieves lubrication of relevantcomponents, but also ensures a complete insulation between the interiorand exterior of the housing 13.

At its bottom central part, the housing 13 has a groove structure 19matching with the structure of the sealing ring 12. Also, studs aredisposed within the housing 13. Through the studs, the motor holder 11can be fixed to the interior of the housing such that no fastenerpenetrating through the housing is required to fix the motor. In someembodiments, the number of the studs can be four.

The brush head assembly includes a brush head 15 and a brush headmounting platform 17 connected to the brush head 15. The brush head 15includes an outer ring and an inner ring, which are connected with eachother through an elastic soft connection 22. The outer ring of the brushhead 15 can be fixed to the housing 13 via a pin mechanism. The bottomof the inner ring of the brush head 15 is provided with aself-lubricating bearing 21 connected to the driving shaft. The brushhead 15 is detachably mounted onto the brush head mounting platform 17,and the mounting can be achieved through a snap-fit connection or acladding, or any other suitable ways of installation. Of course, thebrush head 15 can be integrally integrated onto the brush head mountingplatform 17.

The existence of the elastic soft connection 22 makes the inner ring ofthe brush head 15 only rotates around the driving shaft, with minor orno revolving around its own axis. The self-lubricating bearing 21between the driving shaft and the bottom groove of the brush head'sinner ring also ensures that there can be only minor autorotation or noskidding-like autorotation of the brush head in response to the drivingshaft's movement. Due to the eccentric shaft 14's function, theexistence of the elastic soft connection 22 also enables the brush headto vibrate up-and-down and left-and-right.

In this embodiment, the motor 10 connects with the brush head assemblythrough its own driving shaft and the eccentric shaft 14. The rotationof the motor 10's driving shaft causes the eccentric shaft 14 to rotate.As the other end of the eccentric shaft 14 is coupled to the brush headassembly, the latter is also caused to rotate. In addition, the rotationis further converted by the elastic soft connection 22 into theup-and-down and left-and-right vibrations of the brush head 15.

Of course, it is possible to use a traditional driving mechanism that isso adopted that the rotation of the motor will cause the brush head 15to rotate, instead of the eccentric shaft 14 and the elastic softconnection 22.

FIGS. 3A-3C illustrate a brush head in accordance with an embodiment ofthe present disclosure. FIG. 3A illustrates a front view of the brushhead 15. FIG. 3B illustrates a longitudinal section of the brush head15, the longitudinal section passing through the center axis A-A of thebrush head. FIG. 3C illustrates a distribution of bristle bundles on thebristle implanting surface.

As shown in FIGS. 3A-3C, bristle bundles are substantially in the shapeof a truncated cone in the longitudinal section. The bristle bundles aredistributed in an evenly spaced manner across the bristle implantingsurface. Starting from the center point of the bristle implantingsurface, these bristle bundles are distributed radially, and on thewhole embody a plurality of concentric circular rings. Of course, itshould be understood that the bristle bundles also can be distributed inthe form of concentric square rings.

As shown in FIG. 3C, the distance between the bristle bundles is about2.7 mm. It should be understood that the distance can be set to bewithin a range of 1.5 mm to 3.5 mm.

As shown in FIGS. 3A-3C, the heights of the bristle bundles aregradually lowered along the radial direction, from the center of thebristle implanting surface to outside. This is to clean the deep regionsof an umbilical hole. Referring to FIG. 3A, on the ring closest to thecenter of the bristle implanting surface, the height of the highestbristle bundle is around 22 mm, while after gradual reduction in height,the height of the bristle bundles on the outermost ring is around 3 mm.Also, the heights of the bristle bundles are gradually lowered from theinterior to the exterior at different slopes. In regions adjacent to thecenter region, the slope of height reduction is relatively higher and isaround 2.14, while in peripheral regions the slope of height reductionis abruptly decreased and is around 0.42. It should be understood thatthese designs are mainly made to match with the ergonomic structure ofan umbilical hole. In other embodiments, other heights and slopes may beadopted.

When a cleaning brush is being normally used, it is mainly bristleslocated at its center region that contact the skin of a person to becleaned, and bristles with smaller heights located at peripheral regiondoes not contact the skin. However, considering that some unintendedcontact may be made in the course of cleaning, bristles located atperipheral regions may contact the skin of the person to be cleanedoccasionally. At that moment, bristles located at peripheral regions mayserve as a bumper to avoid the discomfort caused by those people withhighly sensitive skin directly contacting the structural components ofthe brush head, which are typically made from metals or plastics.

It can be learned from FIGS. 3A and 3B that, in the present embodiment,the tips of bristle bundles are rounded and blunted. The resulting shapelowers the irritation that may be made to a human body. Of course, insome embodiments, the tips of bristle bundles are not modified andretain their natural shapes.

In the present embodiment, the bristle's material can be nylon fiber.However, pig hair or wool may be selected according to actual needs.These materials have different softness and can be used for cleaningpeople at different ages. For example, softer bristles may be moresuitable for infants.

Though not shown, it should be understood that, the bristle bundles needto be implanted into the bristle implanting portion at a certain depth.For example, the implanting depth may be 3 mm, which can ensure thatbristles are not easily detached from the bristle implanting portion. Agreater implanting depth also can be contemplated. However, the size ofthe bristle implanting portion as well as the size of the whole brushhead need to be considered, too. As described in the above, in otherembodiments, it is possible to set the cleaning brush's brush shaftportion to be at an obtuse angle (for example 120 degrees, 135 degrees,or 150 degrees), or even an angle of 180 degrees, to its brush headportion, which may be more convenient for some operators to use andallow the brush head portion to have large dimensions (especially indepth). Thus larger bristle implanting depths may be conceivable.

In some embodiments, bristles may be stuck in bristle implanting holesafter being bent by metal sheets. In some embodiments, to preventdetachment of bristles, glue is used at the implanted portions of thebristle bundles to bond bristles. In addition, in some embodiments, atthe opening of each bristle implanting hole and over the bristleimplanting surface, an elastic hoop (not shown) is provided to compactthe bristle bundle.

In some embodiments, bristles are made from materials which areinherently colorful. Those vivid colors which are distinct from the skincolor, such as red, blue, etc., may be selected. As such, even somebristles are detached in an operation, they will be easily discernible,which makes it convenient for medical care personnel to get rid of thesebristles quickly, without causing secondary contamination. Of course,colorful bristles are also more aesthetically pleasing.

In some embodiments, silica gel material can be used to make bristlessuch that each individual bristle constitutes a bristle bundle. It canbe understood that, in this situation, the bristles and the bristleimplanting portion can be integrally formed. One advantage of usingsilica gel material is to better cater to the sensitive skins of somepeople to be cleaned.

In addition, in some embodiments, when in use bristles may be soakedwith certain solvents or solutions (for example iodophor, alcohol,turpentine, etc.). These solvents or solutions may help dissolve mattersto be cleaned off (e.g., foreign substances, fouling, etc.) and adsorbthem onto bristles.

FIGS. 4A-4B illustrate a brush head in accordance with anotherembodiment of the present disclosure. FIG. 4A illustrates a front viewof the brush head, and FIG. 4B illustrates the brush head's longitudinalsection, which passes through the center axis of the brush head.

As shown in FIGS. 4A-4B, the bristle bundle 151 is substantially in theshape of a truncated cone in the longitudinal section. The heights ofthe bristle bundles 151 are gradually lowered along the radialdirection, from the center of the bristle implanting portion to outside.Referring to FIG. 4A, the heights of the bristle bundles 151 aregradually lowered from the interior to the exterior according to asubstantially uniform slope. Specifically, on the ring closest to thecenter of the bristle implanting surface, the height of the highestbristle bundle is around 22 mm. While after being gradually lowered, theheight of the bristle bundle located on the outermost ring is about 5mm.

However, the slope of height reduction is not uniform.Specifically, the slope of height reduction is relatively higher and isabout 3.27 in regions close to the center region, while at peripheralregions the slope of height reduction is abruptly decreased to about0.7. Such a slope design may better match with the shapes of umbilicalholes of some people to be cleaned.

As such, the lengths of the exposed portionsof the bristle bundles 151 located at the center region are shortened.In the case of same material being used, the hardness of this part ofbristles will be increased, which may further enhance its cleaningcapability. Referring to FIG. 10, the protrusion 30 is in the shape of acircular arch, which may help match with the overall truncated coneshape of the bristle bundles. It should be understood that, protrusionshaving other shapes, such as having a truncated cone shape, a multi-stepshape, or a cylindrical shape, may be feasible, too.

Referring again to FIG. 3C, in this embodiment, there is no bristlebundle disposed at the center region of the bristle implanting surface,thus an empty region without bristles is formed at the center region. Asthere is no bristle bundle disposed at the center region, it is notnecessary to provide holes at this region of the bristle implantingportion of the brush head. As such, the firmness of the center regioncan be ensured so that it is not easy for the center region to getbroken. In addition, when the cleaning brush is being used, especiallyin an embodiment of the brush head rotating with the motor, a certainlevel of negative pressure may be produced at the empty region, which isconducive to adsorbing those substances to be cleaned off to thebristles.

FIG. 11 is a schematic view of a brush head in accordance with anembodiment of the present disclosure. In this embodiment, there is nobristle bundle disposed at the center region of the bristle implantingsurface. However, one or more apertures are still provided at the centerregion. The sizes of these apertures may be equal to the sizes of thosebristle implanting holes. In some embodiments, the sizes of theseapertures may be designed to be smaller. The diameters of theseapertures may be contemplated to both increase the negative pressure andensure a certain level of firmness of the structure.

FIG. 12 is a partial section view of a cleaning brush in accordance withan embodiment of the present disclosure. It can be seen that small-sizedfan blades 31 are disposed on the driving shaft of the motor. Unlike atraditional fan, which is blowing forward at the time of rotation, thecurved shape and curvature of the fan blades 31 are designed to blowbackward (i.e., suck the air ahead) at the time of rotating with thedriving shaft. As such, in rotation the fan blades 31 may produce anegative pressure in the central empty region through the apertures,thereby facilitating adsorbing those substances to be cleaned off. Insome embodiments, several apertures are disposed on the housing of themotor holder as well, so as to facilitate air flowing.

Of course, it should be understood that, as the eccentric shaft iscapable of rotating, too, in some instances, the fan blades 31 may bedisposed on the eccentric shaft 14.

Referring to FIG. 13, it is a partial view of a cleaning brush inaccordance with another embodiment of the present disclosure. In thisembodiment, there is a rigid sleeve 32 disposed at the peripheral partof the brush head. For some people to be cleaned, as their umbilicalholes may be relatively deep, it may be difficult to contact the skinsdeep in these umbilical holes by directly using soft bristles. By thisrigid sleeve 32, the umbilical holes may be spread, such that the deepportions now become shallower, and thus easier to be cleaned. This rigidsleeve may be made of a transparent material, such as a tempered glass,as this will help the operator to see what kind of contact is achievedbetween bristles and the skin of the patient.

In some embodiments, the bristle implanting portion is made to bemovable to enable it to be extendable and retractable within the rigidsleeve, so as to achieve a better contact with a patient's skin. Ofcourse, it should be understood that this also can be achieved bydesigning the rigid sleeve as a movable component. For example, thesleeve is slidably fit to the peripheral part of the brush head, bymeans of one or more bumps, where different positions of the bumpsdefine different lengths that the sleeve may extend forward. The bumpsmay be disposed on the inner side of the sleeve, or on the peripheralpart of the brush head.

FIG. 14 is a partial view of a cleaning brush in accordance with anembodiment of the present disclosure. In this embodiment, the brushshaft portion of the cleaning brush is set to be at an angle of 180degrees to its brush head portion. As such, a user may hold the cleaningbrush like holding a pen. In these embodiments, the diameters of thebrush shaft portion and the brush head portion need to be designed to becorrespondingly smaller, so as to be convenient for a user to hold.These pen-like embodiments are especially suitable for cleaningrelatively small orifices such as ear holes or nostrils.

FIG. 15 illustrates a brush head in accordance with yet anotherembodiment of the present disclosure. In this embodiment, the bristleimplanting portion is designed to be in the shape of a pillar structure,and bristles are substantially evenly distributed on the surface of thepillar structure. The bristle implanting portion with a pillar structureis particularly suitable for a pen-like cleaning brush. When cleaningrelatively deep orifices with relatively small diameters (such as earholes and nostrils), such a shape is especially convenient for a user tooperate. However, it should be understood that, it is also feasible touse a bristle implanting portion with a pillar structure in cleaningbrushes of other shapes. In some embodiments, the end of the pillarbristle implanting portion facing a patient's skin is not flat, butdome-like, which makes the spatial distribution of bristles to be moreuniform. In some embodiments, bristles used have multiple colors andbristles of different colors are distributed along the longitudinaldirection of the pillar structure, which can serve as an intuitiveprompt to a user as to how deep have the bristles gone into thepatient's orifice (such as an ear hole, a nostril, etc.).
